RPKI · ASPA
Declared transit providers
This network has signed an ASPA record naming its transit providers. Each is compared against the upstreams observed in routing paths.
| AS | Network | ASPA | Routing paths |
|---|---|---|---|
| AS53173 | Sobral Telecomunicacoes Ltda | Declared | Observed |
An observed upstream that is not declared is not necessarily a leak: our upstream inference cannot tell a transit provider from a peer seen in the same position. A declared provider that is never observed is usually a backup path.
IRR
Registered route objects
Route objects naming AS273671 as origin, across RADb, the RIR registries, ALTDB and NTTCOM. Objects that are registered but not announced come first: a stale object lets anyone who can spoof this origin through an IRR-built filter.
| Prefix | Source | Description | Maintainer | Changed | Routing |
|---|---|---|---|---|---|
| 2804:8a78::/32 | RADB | CLARO S.A. Customer | MAINT-AS4230 | 2024-02-19 | Announced |
